Unformatted text preview: (a) Assume that the metal contains N free electrons per unit volume, and that at X-ray frequency the mean free path of the free electron is very long so that damping can be neglected. Solve the equation of motion for the electron and find the conductivity of the metal as a function of frequency. (The mass and charge of electron are m e and -e ). (b) Assume that the permittivity of the metal is equal to that for vacuum, find the refractive index of X-ray in the metal and hence calculate c as a function of the frequency ω of the X-rays....
